ATOMIZEE.

Specification of Letters Patent.

wanted Dec. 9, 1913.

Application flied September 20, 1912. Serial No. 721,440.

To all whom it may concern:

Be it known that I, GEORGE J. KELLEY, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Atomizers, of which the following is a specification;

My invention relates to atomizers and has for its objects adaptability to uninterrupted discharge, perfect control of the discharge at all times, simplicity of construction with a minimum of parts, convenience in form to adapt the same to use, and facility for removing and replacing and thoroughly sealing the reservoir.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the appended claims. In the accompanying drawings which form a part of this specification,Figure 1, is a side elevation of my atomizer, Fig. 2, a central longitudinal section of the same, and Fig. 3, a bottom plan view of the pump section or casing.

Like reference characters indicate like parts throughout the views.

lily device comprises a casing 3 formed for the manipulation of a single hand, comprising a body portion 4, a base 5 from which the body rises, and a horizontal extension 6 extending forwardly of the body and integral with the same in vertical alinementwith a forwardly extending portion '2' of the base. Mounted in the body of the casing near the rear is a pumping mechanism which in detail comprises a tube 9 provided upon its exterior with threads 10 adapted to engage a threaded opening 12 in the upper portion of the casing, said tube being provided also with an integral annular shoulder 13 upon its upper end resting upon the upper surface of the casing. The inner portion of the shoulder 13 is threaded as at 15 to engage an exteriorly threaded cap 17 provided with a central opening 19 and with smaller air openings 21 and 22. As a sliding fit in the opening 19 passes a plunger or piston member 24 having fixed to its upper end a handle 26 adapted, when the plunger is in its lower position, to contact with the upper surface of the cap 17. The lower end of the tube 9 is closed by a plate27 which may if preferred be integral with the wall of the tube 9. The plate is provided with a central conical depression'28 terminating in a central opening 29.

f Soldered or otherwise fixed to the lower face of the plate 27 or to the wall 9 is a horizontal arm 30 terminating in a loop 31, p which loop is immediately below a conically shaped tap valve 32 of soft rubber, which valve is concentric with the conical depression 28, and loose therein so that it is normally supported upon the arm 30 and loop 31 so as to be slightly interspaced from the material forming the cavity in the plate 27. Cooperating with this valve is a piston 34 upon the lower portion of theplunger, and intermediate the piston and the handle 26 surrounding the plunger 24 is a helical spring 35, which if preferred may be omitted. B manually reciprocating the plunger 24 t e piston 34 operates the valve 32 vertically to alternately open and close the opening 29 thereby supplying air through this opening to an adjacent air chamber 36 within the casing 3.

A bottle or flask 38 contains liquid 39 intended to be sprayed. The top of the flask, as at 40, is retracted to form a neck portion. The bottom of the flask 41 is upwardly inclined toward its rear to conform with the inclined upper surface 42 of the extension 7 of the base 5 The portion 42 constitutes a depression in the casing and around this depression is a circular shoulder or head 44 largely formed by the depression or cavity referred to. In the lower portion of the extension 6 of the casing is a circular recess 45 comprising a body wall 46 and a side wall 47. In the recess 45 is a cylindrical gasket or block'4tl provided with a central opening in which is frictionally held a tube 50. The tube 50 is intended to prevent any inward moving of the material of the gasket 49 when the neck portion 40 of the flask is upwardly pressed against the bottom of the gasket. The upper face of the last mentioned member abuts against the wall 46, and its side against the wall 47 of the casing.

extension 6 of the casing is a horizontal sleeve 52 in which is frictionally mounted a Integral with the upper portionof the tube 54 provided with a passage 55 retracted near one end, and of increased diameter as at56 near the other end, and provided with threads 57. Theopposite end of the tube 54 is of reduced diameter and is provided with external threads 59. An auxiliary or second tube (30, also provided with a central passage 61 coinciding with the passage 55, has its diameter enlarged near one end and threaded as at 63 to engage the threaded end of the tube 54, and a spray tip 62 is threaded or otherwise fixed upon the outer end of the tube 60. One end of the tube 54 is exteriorl threaded as at 65 to receivea milled nut 6 which extends intermediate the sleeve 52 and the tube 54 and projects beyond the end of the member 52. The nut 67 is provided with a central opening 69 through which loosely passes a pin 7 0 having upon one end a milled handle 71, and provided intermediate its length with screw threads 73 engaging the threads 57 of the tube 54. The inner end of the pin is provided with a point 75 which is located in the opening 56, but is adapted to close the passage 55 when the pin is manually turned. In the tube 54 and in the contiguous wall'of the casing are openings 77 and 78 respectively in which are fixed by threads or frictionally a vertical tube 80 which opens into the horizontal passage 56 in the tube 54, and is concentric with and interspaced from the ring 50 and the Wall of the opening 81. It is through the opening 81 and the ring 50 that the air contained in the reservoir 36 enters the flask 38. A rub- .ber tubular section 83 frictionally engages the bottom end of the tube 80 and the upper end of a metallic tube 85. The last mentioned tube has near its top an opening 86 and in its bottom a smaller opening 87. The rubber section-piece 83 forms a joint for the compounded tube 80 and 85 whereby the last mentioned member may be flexed to an inclined or horizontal position to permit the introduction or withdrawal of the flask 38 into or out of position whenever it is essential to replenish the contents of the flask. The member 49 serves as a yielding abutment that permits .jthe flask to betsuitably elevated over the shoulder 44, and when the flask is then released 'it drops into the seat 42 and the resiliency of the material in the member 49 insures a tight closure of the neck portion of the bottle.

By the described construction it will be observed that the casing member comprises a minimum of parts resulting in the absence of numerous joints and the means for sealing the joints and lessening the number of passages that would be otherwise required.

The operation of charging the air reservoir 36 by means'of a pump has already been described. After this charging the casing is held in the operators palm so that the thumb and forefinger grasp the head 71 and turn menses the same to control the discharge of the fluid from the flask through the tubular nozzle-piece 60. The action of the compressed air in the reservoir 36 to discharge the liquid is through the opening 81, the ring 50, and through the perforation 86 into the tube 85. The liquid 39 is, 'b the described course of the air, sucke up through the opening 87 and is mixed with the air coming through the openin 86. Thence the liquid is siphoned or orced through the tubes 83 and 80 past the-conical end 75 of the pin 70 and through the passages 55 and 61 of the nozzle members 54 and 60 respectively. The pin 70 acts as a valve and controls the volume of air and liquid traveling to the nozzle or spray tip 62 through the passages 55 and 61. The conical end 75 of the pin abuts against that portion of the tube 54 adjacent the passage 55 which forms a valve seat 90.
